WILLIAM E. EASTMAN, OF WORCESTER, MASSACHUSETTS.

MlTERlNG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 243,533, dated June 28,1881.

' Application filed July 23, 1877.

To all whom it may concern:

Be it known that I, WILLIAM EVERARD EASTMAN, of the city of Worcester,county of Worcester, audState of Massachusetts, have invented a new anduseful Improvement in Miter-Machines, which improvement is fully setforth in the following specification, reference being bad to theaccompanying drawlugs.

My invention consists, essentially, of the attachment to a reciprocatingsaw-table of adjustable rests, against which moldings or other pieces ofwood to be mitered are held, either by the hand of the operator or byany suitable binding appliance or mechanism.

The rests are shown in position upon the saw-table A, and are designatedby the letters B and B in Figure 1, where they are shown in longitudinalhorizontal section. In Fig. 2 one of the rests is shown in transversevertical section.

In both figures letters of reference are the same.

The rests B B are adjustable in a horizontal direction by the adjustingthumb-screws T TT T, which pass through the ears or projections P P P P,the rests oscillating upon or around the studs S S. The vertical orperpendicular adjustment is obtained by the adjusting-screws H H, which,passing through a projecting portion of the rests, have a bearing uponthe tops of the studs S S. By the screws H H the rests are raised orallowed by their own weight to descend. Theobjectofthehorizontaladjustment is to allow aslight variation from the true miter-angle offorty-five degrees, such variation beingrequisite, under certaincircumstances, to the perfect construction ot a picture-frame. Theobject of'the perpendicular adjustment is to enable the operator toalways hold pictureframe molding with the rest in the rabbet, in-

stead of against the inner edge of the moldin g.

For shallow rabbets the rest is lowered, and for deep or high ones it israised so that afull bearing of the whole insidelsurface of the rabbetmay be obtained. As the dimensions of all )icture-frames are reckonedwithin the rabbet, and not within the inner margin of the frame, animportant advantage of exact measurement by a scale upon and extendingfrom the rests is obtained by allowing the rest to go into the rabbet.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A rest or rests, for the purposes specified, having both a horizontaland a vertical adjustment, said horizontal adjustment being efiected byan oscillatory movement upon a fixed center, and said verticaladjustment by means of a hand-screw,substantiallyas described.
